4 Environmental Analysis 4.7 Geology, Soils, and Paleontological Resources oo Waste management; oo Good housekeeping; and oo Post-construction site stabilization. Prior to initial construction mobilization, preconstruction surveys shall be performed and sediment and erosion controls shall be installed in accordance with the approved SWPPP. GEO-2: Paleontological Worker Education and Awareness Program (WEAP): Before starting construction activities, on-site personnel should be trained in basic recognition of fossils and appropriate procedures to notify management to engage a qualified paleontological specialist in the event that fossils are discovered during construction activities (an unanticipated find). GEO-3: Unanticipated Find Contingency: A qualified paleontological specialist (paleo specialist), meeting the Secretary of the Interior's Professional Qualification Standards for the Society of Vertebrate Paleontology, shall be retained by the Project Owner on an on-call status. The paleo specialist must be approved by both San Joaquin County and Alameda County prior to any on-site activity. The paleo specialist will be brought on-site to evaluate the significance of any unanticipated discovery of paleontological resources (an unanticipated find) and determine if additional study is warranted. If the significance of the find under CEQA or California Public Resources Code, Section 21082, does not warrant such study, the qualified paleontologist may decide to record the find and allow work to continue. If the discovery proves significant under CEQA, preparation of a paleontological treatment, testing, or data recovery plan (Paleo Plan) may be required at the discretion of the paleontological specialist. Any Paleo Plan that is prepared will be submitted for approval, to the appropriate agency within San Joaquin County or Alameda County, depending upon the location of the find. 4.7.6 PG&E Tesla Substation Improvements and Gen-Tie To accommodate the Project, PG&E would be responsible for siting, design, and construction of the gen-tie line from the POCO to its substation. Two options are available for the gen-tie line from this point. The first option would be to connect via an aboveground line from the POCO to a point on the west side of the southwestern boundary of the substation. The second option is to enter the substation on the southwestern edge by way of a belowground line as shown in Figure 2-1 of Chapter 2, Project Description. Either right-of-way corridor is assumed to be up to 100 feet in width. Additionally, PG&E would upgrade the Tesla Substation, and the improvements would include the installation of a grounding system, disconnect switches, surge arresters, outdoor lighting and outlets, and fiber termination for the gen-tie line. The improvements made would be within the existing Tesla Substation footprint. The construction activities associated with the PG&E infrastructure would be required to comply with and adhere to the same design criteria included in the CBC as the rest of the Project components. Construction would be required to comply with requirements of the Construction General Permit, similar to the Project components evaluated above, including implementation of BMPs during construction activities. Subsurface excavation required for the PG&E infrastructure is not anticipated to occur at depths below 10 feet below ground surface.
